Send data packets (100 byte) using mac 802154 and buffer them

[Hamed Agile]

Hello Everyone, I have got confused about my simulations in castalia 3.3. i want to send data packet (100 byte ) in mac 802154. from (node 1, node 2 , node 3 ) to node 4. I want to know whether i need to routing layer and app layer or not. Note: the distance between node 1,2, and 3 with node 4 is one hop. also i want to know that how the node 4 can buffer the received packets and compare them.
